PATENTEDDEC Hen 116269134 SHEET 1 OF 2 Bruce L Mil/er LINE DOG This invention relates to a line-anchoring device or holder for use in building construction.

Many types of line-anchoring devices or dogs are available or have been proposed in connection with the establishment of reference lines to guide the laying of brick or blocks in masonry construction. The prior line anchoring devices are, however, relatively limited in use and are unsuitable for certain size bricks, blocks and types of building frames that may otherwise serve as a reference location. It is therefore an important object of the present invention to provide a lineanchoring device which is more versatile in use insofar as size, texture and shape of bricks or blocks are concerned. Furthermore, an additional object .is to provide a line-anchoring device capable of being mounted on certain types of building frame members. g

In accordance with the present invention, the line-anchoring device is in the form of an elongated body which is rectangular in cross section providing a flat edge adapted to engage a masonry surface along which the guideline extends in certain installations. The guideline is accordingly adapted to be wrapped around the body which is also provided with lateral line-guiding slots by means of which the line may be directed perpendicular to the longitudinal axis of the body in other uses thereof. A dimensionally enlarged head is connected to the body and is externally grooved in order to guide the line in certain directions. A pair of legs extend from the body spaced from the head for anchoring the body in certain installations while a tail extends from the body in a direction opposite to one of the legs to form a dovetail recess with the head in order to anchor the device on the side edge of a door frame. A slot is formed in the head where it meets the body in order to receive the flange portion of a door frame in connection with yet another installation of the anchoring device. Accordingly, the line-anchoring device may be applied in many different ways in all types of masonry construction. Furthermore, the lineanchoring device by virtue "of the aforementioned structural features, eliminates the need for nails and pins often necessary for mounting purposes in connection with prior art anchoring devices. I

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:'

FIG. 1 is a perspective view illustrating a line-anchoring device constructed in accordance with the present invention.

FIG. 2 is a perspective view of the line-anchoring device as viewed from another side.

FIGS. 3 through 7 illustrate the line-anchoring device in various different applications.

Referring nowto the drawings in detail, FIGS. 1 and 2 illustrate a line-anchoring device generally denoted by reference numeral 10 representing an embodiment of the present invention. The line-anchoring device includes an elongated body generally referred to by reference numeral 12 which is generally rectangular in cross section so as to present flat, parallel spaced edges 14 and 16. Formed intermediate the opposite longitudinal ends of the body 12, on the side faces 18 and. 20, are a pair of line-directing grooves 22. Thus, a

guideline wrapped about the body 12 may be directed by laterally outwardly from intermediate portions. The notches directed from the body generally parallel to its longitudinal 1 axis by extending from notches 24 of a depth which increase- 24 confront each other and are formed between the edge 14 of slip foot 30 projecting therefrom at an end remote from the body for gripping engagement with a masonry surface when in use. The foot 30 projects from the front leg 26 in a direction away from the rear leg 28, which is connected to the body at one end thereof. At the same end of the body, a tail 32 extends from the edge 16 in a direction opposite to that of the rear leg 28. The tail 32 is provided with an angled edge 34 to form a dovetail recess bottomed by the body edge 16 with a confronting angled edge 36 formed on a head 38 connected to the body 12 forwardly spaced from the front leg 26 by a neck portion 40.

The head 38 is dimensionally larger in cross section than the body 12 to which it is connected by the neck portion 40 and includes a flat edge 42 equal in width to the edge 14 and coplanar therewith. A parallel spaced edge 44 of the head is interconnected with the edge 42 by an end edge 46 from which the edge 44 extends rearwardly to the angled edge 36 aforementioned, disposed on one side of the longitudinal axis of the body 12 opposite the legs 26 and 28. The head may be provided with a through hole 48 in order to accommodate hanging of the anchoring device.

The edges 42, 44 and 46 are externally formed with interconnected grooves 50 of constant depth. The groove 50 opens into a bore 52 that extends at an angle to the longitudinal axis of the body at neck portion 40. This bore 52 is axially aligned with a semicircular groove 54 formed in the confronting edge 36 of the head. The bore 52 also terminates a slot 56 which extends at the same angle as the bore from one side I8 of the body. Thus, the slot 56'communicates with the groove 50 in the edge 42 of the head through the bore 52 in order to guide thedirection of a line that extends from the anchoring device in one of its applications. 7

A flange receiving slot 58 is also formed in the head 38 in alignment with the planar edge 16 of the body from which it extends into the head. The slot 58 is terminated at a through bore 60 that extends laterally through the head in generally perpendicular spaced relation to the longitudinal axis of the body.

FIG. 3 illustrates the dog 10 applied to the bullnose corner 62 of a block 64 by placing the corner in'abutment with the edge 42 of the anchoring device which is at right angles to the front leg 26 in gripping engagement with the block by means of its foot 30. It will of course be appreciated, that the lineanchoring device may also be applied in the same fashion to a regular corner block. In the application illustrated in FIG. 3, the guideline 66 is wrapped about the body I2 of the anchoring device an extends from one of the notches 24 to the lateral slot 56 through which it is guided into the groove 50 in the edge 40 from which the guideline extends along one rightangle edge surface of the block 64. In FIG. 4, the anchoring device is firmly wedged in place by means of the legs 26 and 28 so that the coplanar edges 14 and 42 of the body 12 and head 38 may engage the top surface of a course of bricks 68 along which the guideline 66 extends from the notch 24 between the body and the rear leg 28. The front leg 26 is inserted for this purpose between the webs or within the holes formed in the brick with the longitudinal axis of the body extending at an angle to the face of the brick. The anchoring device as shown in FIG. 4 may similarly be applied to the top edge of a block in a block wall construction.

FIG. 5 illustrates the line-anchoring device 10 secured to a door frame 70 framing an opening in a block wall 72. In this installation, the anchoring device is mounted on the door frame 70 by inserting the flange 74 of the door frame-into the slot 58 so that the body 12 extends in a horizontal plane generally perpendicular to the vertical surface of the block wall 72. A guideline may either extend at right angles-to the longitudinal axis of the body 12 from the groove 22 as shown by dotted line in FIG. 5 or may extend from the notch 24 between the body and the rear leg 28 at an angle to the longitudinal axis of the body 12 in alignment with the vertical surface of another block wall 76 disposed at an obtuse angle to the wall 72. Thus, the guideline extends from the anchoring device as shown by solid line in FIG. 5 and is wrapped about the tail 32.

in FIG. 6 the anchoring device 10 is mounted on a door frame 78 by receiving one side of the door frame within the dovetail recess formed between the tail 32 and the confronting edge 36 of the head 38. In this application of the anchoring device, the edge 44 of the head 38 engages the vertical surface of the block wall 80 on which the door frame 78 is mounted so that the guideline 66 may extend from the the groove in the edge 44 along the verticalsurface of the wall. The guideline in this application is wrapped about the front leg 26 and extends from notch 24 between the body 12 and the front leg to the edge 44 of the head.

A pair of anchoring devices 10 and 10' are respectively mounted by the legs thereof on the top edges of corner blocks 82 and 84 as shown in FIG. 7 forming an obtuse angular comer with guidelines 66 and 66 extending from the heads of the anchoring devices in alignment with the inside and outside corners of the block 'wall.

From the foregoing description, the versatility of the anchoring device of the present invention will be apparent. The anchoring device may be mounted in position without use of levels as long as the corner or course of bricks or blocks is set. Further, the anchoring device may be mounted without use of line pins or nails and may be applied to all types and size masonry walls, door frames and comers.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
